VPN through proxy servers

I have 2 domains that each connect to the internet via proxy server over cable modems. I'd like to establish a VPN using PPTP and RRAS between them. I've read all the docs and newsgroup posts, and still no luck. My headach comes from the fact that when Itry to add a PPTP interface in RRAS, I get a message saying "WAN routing is required to add and interface".The Proxy servers are also the PDCs and the RRAS all at the same time. I've got packet filtering set, with certain exceptions defined for both sides, including the inclusion of the PPTP Call and Recieve, and NETBIOS exception for the remote IP address.It's a complex environment, I know, but I'm bound by the customer's requirements.

VPN through proxy servers

stupid answer, but did you install the PPTP protocol from the protocols tab in the network control panel.

did you make sure that after installing PPTP that you added some vpn adapter in the network control panel --> services tab--> RRAS--> properties window.

If you did add these vpn adapters, in this same window, click on one and click configure. Make sure you have atlease one adapter with the "dial out and recieve calls as a demand dial router" checkbox. If you don't see this check boxreinstall RRAS and enable demand dial routing during installation.

Also make sure you have IP forwarding set in the TCP/IP properties sheet
